Case Type   : 事件触发器
Case Name   : 【事件触发器】CREATE/ALTER/DROP VIEW命令触发事件触发器
Create At   :2024/07/08
Owner       :sungang14
Description :
    预置条件：
        1.创建事件触发器：
        CREATE OR REPLACE FUNCTION f_eventtrigger_0010()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
        CREATE EVENT TRIGGER start_eventtri ON ddl_command_start EXECUTE PROCEDURE f_eventtrigger_0010();
        CREATE EVENT TRIGGER end_eventtri ON ddl_command_end EXECUTE PROCEDURE f_eventtrigger_0010();
        CREATE EVENT TRIGGER drop_eventtri ON sql_drop EXECUTE PROCEDURE f_eventtrigger_0010();
        CREATE EVENT TRIGGER rewrite_eventtri ON  table_rewrite EXECUTE PROCEDURE f_eventtrigger_0010(); 
       2、创建表
        CREATE TABLE t_eventtrigger_0010(id int, col int);
    测试步骤：
        1、create view v_eventtrigger_0010 as select * from t_eventtrigger_0010;
        2、ALTER VIEW v_eventtrigger_0010 RENAME TO newt_v_eventtrigger_0010;
        3、DROP VIEW newt_v_eventtrigger_0010;
Expect      : 
    1、触发执行函数f_eventtrigger_0010()
        test_event_trigger: ddl_command_start,CREATE VIEW
        test_event_trigger: ddl_command_end,CREATE VIEW
    2、触发执行函数f_eventtrigger_0010()
        test_event_trigger: ddl_command_start,ALTER VIEW
        test_event_trigger: ddl_command_end,ALTER VIEW
    3、触发执行函数f_eventtrigger_0010()
        test_event_trigger: ddl_command_start,DROP VIEW
        test_event_trigger: sql_drop,DROP VIEW
        test_event_trigger: ddl_command_end,DROP VIEW
